Description

Technical Field

[0001] This utility model relates to the field of punch press equipment technology, and in particular to a punch press with a feeding and positioning mechanism. Background Technology

[0002] A punch press is a stamping press. In national production, stamping technology has become increasingly widely used due to its advantages over traditional machining, such as saving materials and energy, high efficiency, low operator skill requirements, and the ability to produce products that cannot be achieved by machining through the application of various molds.

[0003] Stamping production is mainly for sheet metal. Using dies, it is possible to produce punched, formed, drawn, trimmed, fine-stamped, shaped, riveted, and extruded parts, which are widely used in various fields.

[0004] Existing punch presses generally lack the function of conveying and positioning the workpiece, which cannot meet actual processing needs. Utility Model Content

[0005] (1) Technical problems to be solved

[0006] This utility model provides a punch press with a feeding and positioning mechanism, which overcomes the shortcomings of existing punch presses that generally do not have the function of conveying and positioning the workpiece, and cannot meet the actual processing needs.

[0007] (2) Technical solution

[0008] To solve the above-mentioned technical problems, this utility model provides a punch press with a feeding and positioning mechanism, including a frame, a punch press body, a first synchronous belt conveyor, a worktable, a positioning mechanism, a second synchronous belt conveyor, a screw, a drive motor, a fixed plate, a moving block, and an upper support assembly. The punch press body is horizontally mounted across both sides of the top of the frame. The worktable for placing workpieces is provided on the top of the frame directly below the punch press body. The first synchronous belt conveyor and the second synchronous belt conveyor are respectively mounted on the top of the frame on one side and the other side of the worktable. The machine is equipped with a positioning mechanism for positioning the workpiece. The positioning mechanism includes a first cylinder and a positioning plate. The first cylinder is mounted on the worktable. The positioning plate is connected to the first piston rod of the first cylinder. The screw is rotatably mounted between the two sides of the middle part of the frame. The screw is driven by the drive motor. Two moving blocks are threadedly connected to the screw. A connecting block is connected between the upper ends of the two moving blocks. Two upper support components for lifting the workpiece upward are provided on the top of the connecting block. The worktable has a gap for the upper support components to move upward.

[0009] Preferably, a fixing plate is fixed between the two sides of the frame below the screw, and a moving groove is provided on the fixing plate, with the lower end of the moving block slidably connected to the moving groove.

[0010] Preferably, the distance between the two upper support components is equal to the distance from the gap to the discharge end of the first synchronous belt conveyor and the distance from the gap to the feed end of the second synchronous belt conveyor.

[0011] Preferably, the upper support assembly includes a second cylinder, a second piston rod, and a support plate, wherein the second piston rod of the second cylinder is arranged facing upward and its upper end is connected to the bottom of the support plate.

[0012] (3) Beneficial effects

[0013] This invention provides a punch press with a feeding and positioning mechanism, overcoming the shortcomings of existing punch presses which generally lack the function of conveying and positioning workpieces, thus failing to meet actual processing needs. Compared with the prior art, this invention has the following advantages: By activating the second cylinders of the two upper support components, the second piston rods are driven to move upwards, lifting the workpieces on the discharge end of the first synchronous belt conveyor and the worktable via two support plates. The drive motor is then activated again, driving the screw to rotate and thus moving the moving block, transferring the stamped workpieces to the second synchronous belt conveyor for transport. Simultaneously, the workpieces to be stamped are transferred to the worktable. Activating the first cylinder drives the first piston rod to move, thereby driving the positioning plate to position and clamp the workpieces. After positioning, stamping is performed. This process is repeated to achieve feeding before processing, positioning during processing, and feeding after processing, thus meeting production requirements. Attached Figure Description

Detailed Implementation

[0018] The present invention will be further described in conjunction with the accompanying drawings and embodiments.

[0019] like Figures 1-3 As shown, the punch press with a feeding and positioning mechanism of this utility model includes a frame 1, a punch press body 2, a first synchronous belt conveyor 3, a worktable 4, a positioning mechanism 5, a second synchronous belt conveyor 6, a screw 7, a drive motor 8, a fixed plate 9, a moving block 10, and an upper support assembly 12. The punch press body 2 is horizontally mounted across the top two sides of the frame 1. The worktable 4 for placing the workpiece 13 is provided on the top of the frame 1 directly below the punch press body 2. The first synchronous belt conveyor 3 and the second synchronous belt conveyor 6 are respectively mounted on the top of the frame 1 on one side and the other side of the worktable 4. The worktable 4 has positioning mechanisms for the workpiece 13 at both ends. The positioning mechanism 5 of part 13 includes a first cylinder 51 and a positioning plate 53. The first cylinder 51 is mounted on the worktable 4. The positioning plate 53 is connected to the first piston rod 52 of the first cylinder 51. The screw 7 is rotatably mounted between the two sides of the middle part of the frame 1. The screw 7 is driven by the drive motor 8. Two moving blocks 10 are threadedly connected to the screw 7. A connecting block 11 is connected between the upper ends of the two moving blocks 10. Two upper support components 12 for lifting the workpiece 13 upward are provided on the top of the connecting block 11. The worktable 4 is provided with a gap 41 for the upper support components 12 to move upward.

[0020] The fixing plate 9 is fixed between the two sides of the frame 1 below the screw 7. The fixing plate 9 has a moving groove 91, and the lower end of the moving block 10 is slidably connected to the moving groove 91.

[0021] The distance between the two upper support components 12 is equal to the distance from the gap 41 to the discharge end of the first synchronous belt conveyor 3 and the distance from the gap 41 to the feed end of the second synchronous belt conveyor 6.

[0022] The upper support assembly 12 includes a second cylinder 121, a second piston rod 122, and a support plate 123. The second piston rod 122 of the second cylinder 121 is arranged facing upward and its upper end is connected to the bottom of the support plate 123.

[0023] In actual operation, upon first use, a workpiece 13 is placed on the workbench 4. The first cylinder 51 is activated, driving the first piston rod 52 to move, which in turn drives the positioning plate 53 to position and clamp the workpiece 13. Then, it is used in conjunction with the punch press body 2 for stamping production. The remaining workpieces 13 are transported by the first synchronous belt conveyor 3. The drive motor 8 is activated, driving the screw 7 to rotate, which in turn drives the moving block 10 to move. When the two upper support components 12 move to the bottom of the discharge end of the first synchronous belt conveyor 3 and the bottom of the gap 41 of the workbench 4, respectively, the drive motor 8 is turned off, and the second cylinder 121 of the two upper support components 12 is activated, driving its second piston rod 122 upward. The movement uses two pallets 123 to lift the workpiece 13 on the discharge end of the first synchronous belt conveyor 3 and the worktable 4 respectively. The drive motor 8 is started again to drive the screw 7 to rotate, which in turn drives the moving block 10 to move, transferring the stamped workpiece 13 to the second synchronous belt conveyor 6 and conveying it out. At the same time, the workpiece 13 to be stamped is transferred to the worktable 4. The first cylinder 51 is started to drive the first piston rod 52 to move, which in turn drives the positioning plate 53 to position and clamp the workpiece 13. After positioning, stamping is carried out. This process is repeated to realize the feeding of the workpiece 13 before processing, the positioning during processing, and the feeding after processing.
